This invention relates to a device for molding plant covers, and itsobjects are to provide elements whereby a sheet of suitable paper orother material may be formed,

and prepared surfaces therefor, from insects, and from the deleteriouseffects of wind, rain, and inclement weather. I v Other objects are toprovide apparatus of this character," embodying -,simplicity,citiciency, and ease ofmanipulation in use.

In the drawings: Figure 1 is a perspective view of a mold deviceembodying the present invention, showing the male mold member. 2 is aperspective detail view of a cutter adapted for'trimming the edge of thecover. v Fig. 3 is a perspective mold member. Fig. 4C

sectional view of the mold member, showing the spacing elements mountedthereon, Fig. 5 is a fragmentary and detail view of-the clip holder forretaining the material in position in the initial steps of the formingprocess.

Referring to the drawings, the base'll, is provided with an annulargroove '12, space apart from 13. A clip member 14, is adapted to retaina sheet of paper-or other material to be molded, in position upon thedome portion 13. The cooperative mold member 16, has a flange 17,extending therefrom, and hasthree rollers 18, mounted therein, andprojecting therefrom, wherebyv the mold member'may be turned easily uponthe sheet of material. Other spacing elements consists of balls 19,projecting inwardly throughv apertures 20, and actuated by springs 21.

I provide a handle 24;, for the manualmanipulation of'the upper mold member. The mold members 13 and 16 arepreferably made of a cover the forming dome.
